Not as written if you want the 2nd and 3rd grep to have been parallelized.
As written, only the 1st zgrep will be.
Try this instead:
parallel ‘zgrep foo {} | grep bar | grep 192.168.1.100’ ::: 201612*.gz

Subject: output of parallel pipe to another grep
Hi I have multiple compressed files that I need to run grep against.
I am trying to find 'foo', 'bar' and '192.168.1.100' against all the compressed
log files.
This will work?
ls 201612*.gz | parallel zgrep foo {} | grep bar | grep 192.168.1.100
Thanks for such an awsome tool!

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
